upgrade

[Thomas Lange]

Hi,

there's this long rcS_fai script that calls install_packages and
defines all environment variables, that are needed. FAI_ROOT and
classes must be defined maybe other too. fai has no mechanism to call
a command on every node of a cluster (push method), it uses a pull
method, so every node get it's command to execute.  For upgrading you
do not need fai. Try this little script

#! /bin/csh

set clustername=node

foreach h (01 02 03 04 05 06 07 08 09 10 11 12 13 14)
   set host = $clustername$h
   ping $host 1 >/dev/null
   if ($status == 0) then 
         echo ''
         echo ''
         echo '*****   '$host'   *****'
         rsh $host apt-get update
         rsh $host apt-get -f -y upgrade
   endif
end
